BALL-BEARING.

Application filed @111 1-5,

To all whom it may concern:

Be it known that we, Ross 55. Pnimirs, Mine HARRIS, and JOHN F. nurture, eitizens of the United States, residing at James town, county of Chautauqua, end'Stote of New York, have inventedcertein new and useful Improvements in Bdlldieerings, of which the following, taken in connection With the accompanying drevings, is 9. full,

clear, and exact description.

The invention relates to bell-bearings for heavy duty; and the objects of-our invert tion ere, first, to rovide a novel method for .assembling end olding the parts of ballhearings in place; andseconcl, to provide simple cheep end durable nieensfo r adjusting the bell races to the halls end so securing them in theedjusted position at to make 2 perfect fit of thebsll-race on the bells, and in; such a manner also that the bee rin%) moy be tjzen sport for the insertion of no ells and readjusted with the some high degee of securacy of adjustment between the parts.

In the drevings, Figure 1 's e crosswise sectional View of a bearing her ing two rows. of bells, and showing our method of con struction. Fig. 2 is a sectional View of one half of the boll-beering at line Xi; in Fig. 1.- Fig. 3 is a sectional View of a modified form 'ot the bearing with two rows of balls yyide apart and showing our edjusteble spre-sder; and Fig. 4 is a similar sectional view of a Wide bull-hearing arranged for s coininon shop hsngerend with closed ends; end Fig. 5 is o similar sectional View showing the adopts.-

tion of the bearing with three rows of bulis to ti heel hubs. Fig. 6 is a si e elevation of a Z liOdlfiilsZtiOD of the ball-beefing showing its adaptation to e. shaft hanger; and Fig. 7 is :1. vertical sectional view of the modification of the beering as attached to the lower end of the shaft hanger.

Similar numerals refer to corresponding ports in the several views.

The numeral 10 in Figs. 1 end 2 indicates the t'w'o hardened steel parts of the outer double race-ring having the bell-races 11 "for bolls12 formed h the trel annular projections 13 on the inner face. Said ring so parts 10 adjusted with a space b I then and have the cup-1i e openin 's "l ljztcent faces, for a purpose l c .irth.

its outer face formed by the outer annular flange-like projections 17.

To assemble the bearing a full row of balls is inclosed between the inner ring 15 and one of the parts 10 of the outer ring, by turning the rings on their edges upon a suitable supporting surface. Then the other portion 10 of the outer ring is placed upon the first portion shutting down so for post the projection 17 as to allow of the insertion of the second row of bulls. After having proceeded thus 6') for in order to secure the high degree of uccuracy necessary in the adjustment of the bulls in the races, on inilepeni'lent assembling ring 18 is placed on the supporting surface. (See dotted lines in Fig. 1.) The ring 18 is a 7 close lit to the outer side 01'' the lower part 10 01 the outer race-ring and extends up the Width 01 port 10 in'such close fit. it then extends out in an annular flange 19 which leaves an opening 20 adjacent to the ring 10 throughout its circumference. A number of set screws 21 having pointed inner ends are provided in thefian 'e 19, thepoints extending into the opening between rings 10. I The set screws 21 pr es the rings 10 apertuntil perfect adjustments or" the races 11 and 16 are attained on the balls 12. After securing this perfect sdjustment, the space 22,1betweentl e ports 10 ()1 the outer ring is filled with fus ble metal, that is, metal which melts st low temperature-such as Babbitt-metal or the like, the on l ke openings l l'locking the fusible metal firmly in place. The inner spsce between the bells is protected by being packed with suitable material so that thefusible metal will not extend into t1 e path of the balls. The assembling rin 1 is then removed and the projecting fusible nietol on the outer side of the ring is out sway, after which the outer faces may be properly ground and thebeoring is ready to be placed in a suitable housing. The-fusible metal holds the perfect accuracy of of the rece woys on the bells attained by the set screw'2l.

in the modified forms of'beurings shown in Figs. 3, 1, and 5 the screw method of udjustnic'nt is adopted to bearings having perrnze nent outer housings 27, 27, and 27 undeither two or three rows oi bulls Widely separated and upon either orboth rings 11). lhis is a complished by :tension 23 at one side oi" th inner rat" 15 or 15". The

ring 15,150115 portion.

having a similar threaded projection 23 extending toward projection 23 on the first part ol said ring. A cylindrical ring 2.3 is provided with threads on its inner surface to engage projections 23 and act as a spreader lor the two parts of the inner rings, by means the thread and cups 14, as shown .in Figs... 3

and t, and thereby forming an absolute leek for the parts so that they cannot get out of adjustment and rendering permanent that perfect fit which is so necessary to the proper working of a ball-bearing. .ln Fig. 5 is shown the application of this principle to the hubs of wheels, as in wagons, automobiles r and like vehicles, in which a double ballbearing is placed atrth'e rear of the hub and a single bearing at'the outer end, the two sections being connected by the adjusting ring as above described. 1

In the modification shown in Figs. 6 and 7 a simple and. cheap form of our balhbearing is shown as applied to a shaft hanger. in this form the parts 10 are made from sheet steel in the form of steel stanipings and 27, the inner edge of rings 10 being turned in races 11 by means of a suitable die.

u .Tlie pointed set screws 21 are inserted in the outer ring 27' so that the parts 10* may be adjusted to a high degree of accuracy upon balls 12. Openings 28 are provided in outer ring 27 through which the fusible metal is poured thereby filling the space 29 between the parts 10 and,- the outer ring 27 which space corresponds to the opening 22 as shown in Fig. l. The fusible metal serves the same purpose of locking the parts of the ring firmly in place, supporting the same, and renderingperrnanent the fitof the rings on the balls. This'form of a bearing is assembled in much the same manner as above described for the form shown in F 1. For use on shafting the outer ring 27 has a stem 30 which is inserted in an opening in the lower end of a haner 31 end'vertically held and adjusted ther in by neans of a bolt 32 after which it is fixed in position by means of set screws 33.

. It is important that the bearings should be protected frerndust and dirt whether nsed on vehicles or shafting Accordingly a screw cap closure 34 is prov ded for the outer ends of vehicle bearings as shown. in Fig. 5, the

sup-- ported by a permanent outer ring or housing adjusted position.

1 shown in the sheet metal stamping covered a convenient form of this cap is shown for shalt bearing in section in Fig. 7.
